No, not the historical information on where certain colors were traditionally worn. I was referring to your assertion that black, charcoal and dark colors should be worn in an urban environment because they simply look better in that environment than brown and other lighter colors. I'm not sure how you can objectively state that any specific color looks better in an urban environment, especially considering the vast diversity of our many urban environments.
If you're in Gotham City, or a soot covered 1750 London, I could see it. However, I don't live in a bleak post-apocalyptic world so navy and brown is just fine in every city I've ever been to.
